Do you know what he was impeached for? When Yulia Tymoshenko dealt with Gazprom, she pocketed the cash; when Yanukovich dealt with Gazprom, the funds went to the treasury. But Tymoshenko gets released from prison and Yanukovich gets exiled. But funny thing is when rebels had literal guns to their heads, the parliament changed their opinion of who was innocent and who was guilty.

I believe the timeline was more closely: Yanukovich put Tymoshenko in prison (rightly or wrongly), then he tried to seize more power for himself, then his people revolted (in the west, the Russians are big on the distinction), he shot them, he was impeached, and he fled.
